I have spark LT model car. But just before 1 month, noise comes from rear side of the car when car passes bumpy roads. Initially i thought it comes from rear suspension and Back suspensions are replaced under warranty by the dealer, but the problem persists. Now also i hear noise from the front side in rough road.

Tire and alignment shops are the best at finding these types of noises.

Here in the U.S. many auto parts stores rent or borrow tools for do-it-yourselfers. There is a tool you might be able to borrow called the "Chassis Ear". It is a set of six microphones, a switch box, and headphones. You clip the microphones to suspect points, then drive around while listening with the headphones. You can move the microphones around to zero in on the source of the noise. Be aware that many mechanics have never seen or even heard of this tool. Suspension and alignment mechanics use it to find rattles, squeaks, and other noises.
